| 摘要: |
| 采用电镀方法分别在铜基体上制备了纯银镀层和银石墨复合镀层，并采用X射线衍射仪（XRD）和扫描电镜（SEM）确定了镀层的结构和成分。用MFT-R4000高速往复摩擦磨损试验机，考察不同镀层在润滑条件下的摩擦磨损性能；用MFT-R4000载流往复摩擦磨损试验机，考察了载流条件下复合镀层的摩擦磨损性能；用HLY-200A回路电阻测定仪测定镀层的导电性。用SEM和X射线能谱分析仪（EDX）观察和分析磨痕表面形貌及元素组成。结果表明，银石墨复合镀层不但提高了摩擦副的抗磨和减摩性能还提高了材料的导电能力，降低了接触电阻。 |

| Abstract: |
| Silver and Ag-graphite composite coatings based on the copper substrate were prepared by electroplating. Phase constituents and morphology of the coatings were determined by X-ray diffraction (XRD) and the scanning electron microscopy (SEM). Tribological properties and electrical conductivities of these plating materials were tested by MFT-R4000 high speed reciprocating friction and wear tester, MFT-R4000 current-carrier friction and wear tester and HLY-200A circuit resistance tester, respectively. SEM and energy-dispersive X-ray spectroscopy (EDX) were employed to analyze the wear surfaces and typical elements. Results show that the composite coating can improve the conductivity of the substrate material and improve the antifriction and wear resistance property. |
